Thelocking assembly 30 has a locking position and an avoiding position, and thelocking assembly 30 has asecond snap structure 31 cooperating with thefirst snap structure 21. When thelocking assembly 30 is in the locking position, thesecond snap structure 31 is snapped with thefirst snap structure 21 to limit the movement of theshaft sleeve 20; when thelocking assembly 30 is in the avoiding position, thesecond snap structure 31 is spaced apart from thefirst snap structure 21 such that theshaft sleeve 20 is rotatably arranged on themounting housing 10. Specifically, thefirst snap structure 21 in this embodiment may be a snap groove, thesecond snap structure 31 may be a snap protrusion, and the snap protrusion is snapped into the snap groove to restrict the rotation of theshaft sleeve 20. - By adopting the locking mechanism according to this embodiment, when the movement of the
shaft sleeve 20 needs to be limited, thelocking assembly 30 is in the locking position, so that thesecond snap structure 31 of thelocking assembly 30 is snapped with thefirst snap structure 21 on the inner wall of theshaft sleeve 20, thereby effectively ensuring the stability of the position of theshaft sleeve 20 and avoiding the position shifting of theshaft sleeve 20. When theshaft sleeve 20 needs to be operated, thelocking assembly 30 is in the avoiding position, so that thesecond snap structure 31 of thelocking assembly 30 avoids thefirst snap structure 21 on the inner wall of theshaft sleeve 20, and then theshaft sleeve 20 is rotated. Therefore, the locking mechanism according to this the embodiment enables convenient operation and improves the ease of use for users. - In order to better drive the movement of the
locking assembly 30, the locking mechanism in this embodiment further includes adriving member 40, and at least a part of the drivingmember 40 is movably arranged on and passes through the mountinghousing 10. Thedriving member 40 is in driving connection with at least a part of thelocking assembly 30 to drive thelocking assembly 30 to move to the locking position or the avoiding position.

Specifically, theanti-loosening gasket 50 in this embodiment is a wedge-shapedanti-loosening gasket 50, which can solve the problem concerning the preload force provided by the user during bare-handed rotation of thedriving member 40, reduce the preload force of 17 KN required by conventional knobs to 2 KN, and ensure that the locking mechanism does not become loose due to vibration during use. - Specifically, the
locking assembly 30 in this embodiment further includes a pushingblock 32 movably disposed within theshaft sleeve 20 and alocking portion 33, and the drivingmember 40 drives the pushingblock 32 to move in an axial direction. Thelocking portion 33 is arranged along a peripheral edge of the pushingblock 32, and thesecond snap structure 31 is arranged on a side of thelocking portion 33 away from the pushingblock 32 to push thelocking portion 33 to move in a radial direction by means of the pushingblock 32, so that thesecond snap structure 31 avoids thefirst snap structure 21 or thesecond snap structure 31 is snapped with thefirst snap structure 21. Specifically, thedriving member 40 in this embodiment is in driving connection with the pushingblock 32, thedriving member 40 is rotatably arranged, and thedriving member 40 drives the pushingblock 32 to move in the axial direction so that thelocking portion 33 at the peripheral edge of the pushingblock 32 expands or contracts in the radial direction by means of the pushingblock 32, thereby making it convenient for thesecond snap structure 31 to be snapped with or avoid thefirst snap structure 21 on the inner wall of theshaft sleeve 20, which in turn facilitates control over the movement of theshaft sleeve 20.

Specifically, theshaft sleeve 20 also has a third connection opening 24 between thefirst connection opening 22 and the second connection opening 23, and the third connection opening 24 is used to couple a vertical tube of the scooter. - In order to improve the mounting stability of the mounting
housing 10, the mountinghousing 10 in this embodiment further includes a connectingblock 13 arranged between the first mountingplate 11 and the second mountingplate 12, to connect the first mountingplate 11 and the second mountingplate 12 through the connectingblock 13, thereby improving the stability of the arrangement of the first mountingplate 11 and the second mountingplate 12. At the same time, it is possible to facilitate stable rotation of theshaft sleeve 20 on the mountinghousing 10. - In this embodiment, the locking mechanism further includes a
decoration button 60, acover plate 70, and arubber sleeve 80. Thedecoration button 60 is arranged at a side of the mountinghousing 10 away from the driving button, to improve the aesthetics of the appearance. Thecover plate 70 is arranged on thedecoration button 60. Thedecoration button 60 is provided with a through hole, the drivingrod 41 movably passes through the through hole, and thecover plate 70 covers the through hole to prevent the drivingrod 41 from extending out of the through hole, which can avoid a situation that the drivingrod 41 falls out due to too many rotation turns of the drivingknob 42. Therubber sleeve 80 is fitted over at least a part of the connectingblock 13. The first mountingplate 11 is coupled to the connectingblock 13 by screws, and the second mountingplate 12 is coupled to the connectingblock 13 by screws. Specifically, the connectingblock 13 has an X-shaped structure with threaded holes at four ends of the X-shaped structure, and one or more columnar structures may be arranged on the X-shaped structure and configured to place therubber sleeve 80. Specifically, in this embodiment, one columnar structure is milled at a threaded hole on an upper right side of the X-shaped structure; therubber sleeve 80 is fitted over the columnar structure; the screw passes through a through hole in the first mountingplate 11 and then is connected with the corresponding threaded hole; meanwhile, therubber sleeve 80 will be squeezed and undergo certain elastic deformation. By arranging therubber sleeve 80, the risk of loosening after long-term use can be reduced, and the stability of the whole structure can be improved. - In this embodiment, the second mounting
plate 12 is provided with a mounting hole, and theguide block 34 is pressed in the mounting hole in an interference manner. - By adopting the locking mechanism according to this embodiment, in a locking mode of rotary expansion, the locking action or the unlocking action can be satisfied simply by rotating the driving
knob 42 by two turns, and the design of retaining structure can effectively prevent the knob from coming out, and upgrade the user experience during operation. - A second embodiment of the present disclosure provides a vehicle including the above locking mechanism. The vehicle may be a scooter, a bicycle, and etc. In specific implementation, the vehicle includes a vehicle body, a locking mechanism, and a vertical tube; the mounting
housing 10 of the locking mechanism is arranged on the vehicle body; and the vertical tube is arranged on theshaft sleeve 20 of the locking mechanism. The vertical tube and the vehicle body can be simply and reliably locked by adjusting the locking mechanism. - It can be seen from the above description that the above embodiments of the present disclosure achieve the following technical effects: the ease of manipulation of the locking mechanism is improved, the anti-loosening effect is effectively achieved, the user experience is upgraded, and the operation stability of the whole structure is enhanced.

Also, it is to be understood that the dimensions of various components illustrated in the drawings are not drawn in relation to actual scale, for ease of description. Techniques, methods and devices known to those of ordinary skill in the related art may not be discussed in detail, but should be considered as part of the granted specification in appropriate situations. In all examples shown and discussed herein, any particular value should be construed as merely examples only and not as limitation. Thus, other examples of illustrative embodiments may have different values. It should be noted that similar numbers and letters refer to similar items in the drawings, and thus, once an item is defined in one figure, no further discussion of it is required in subsequent figures.
